 but which are used less frequently by users:

    bin2v              Convert a binary file to a v source file,

    check-md           Check that V examples in markdown files are formatted and can compile.
 
+   setup-freetype     Setup thirdparty freetype on Windows.

    test-all           Run most checks, that the CI does locally.
                       It may take over 2 minutes, and it needs internet connectivity too,
                       because it tries to also verify that `v install` works.
 
    test-fmt           Test if all files in the current directory are formatted properly.
 
-   test-self          Test if V is working properly by running all tests, including the compiler ones.
-                      NB: this can 1-2 minutes to run.

    test-parser        Test that the V parser works with the given files, as if
                       they were typed by a human programmer, one character at a time.
                       NB: *very slow* for longer files (tens of seconds for 1KB .v file).
                       Mainly useful as a parser bug finder for the V Language Server project.
